Hey,

i ´m trying to remember a movie which i saw as a kid either in late ´80 or early ´90, it was a tv sci-fi movie for kids, in which there were  two kids (a boy and a girl if i remember correctly), and there was some kind of monster or alien invasion, and the monsters were like…big piles of hay, or turd 🙂 i dont remember much more about except that at some point the kids were running in some sort of underwater tunnels, being chased by these creatures, and they managed to escape by squeazing through some membrane in some of the tunnels, and in the final scene kids emerged from  the sea (might not be the final scene, ii can be wrong), so the tunnels were under the sea, or something… So if you could pinpoint the movie, i would greatly appreciate it 😀
